Electronic Medicines Compendium (eMC) is provided by Datapharm Communications, a non-profit-making subsidary of the Association of the British Pharmaceutical Industry (ABPI). The eMC is the definitive up-to-date guide for UK medicines information. The eMC has two types of information about most medicines available in the UK. These documents are the Summary of Product Characteristics and Patient Information Leaflets. Both are produced by the manufacturer when a medicine is first produced and then kept up-to-date as more is discovered about the medicine. Currently 140 pharmaceutical companies support the eMC.
